ECG leads (I, II, III, aVF, V1 & V6) and intracardiac recordings (from the coronary sinus-CS, His bundle electrogram -HBE and right ventricular apex-RVA) display the simultaneous recordings of atrial and ventricular electrogram consistent with AVNRT.

A case is presented of use of electro-anatomical mapping (EAM)-guided ablation of a slow pathway in a patient with symptomatic atrioventricular (AV) nodal reentrant tachycardia (AVNRT) as a safeguard against inadvertent AV block. Rhythmos 2022;17(4):79-80.

Context 1
... the EPS, a narrow-QRS tachycardia (cycle length 304 ms) with 1:1 atrioventricular (AV) ratio was easily induced during rapid atrial pacing while assessing AV conduction. Intracardiac recordings confirmed AV nodal reentrant tachycardia (AVNRT) as its mechanism (Fig. 1). A jump in the AH interval could not be determined due to readily inducible tachycardia with any atrial extrasystolic stimulation but was obvious during the initiation of the AVNRT. Subsequent to the induction of the tachycardia and the determination of its mechanism, a set-up was planned and arranged to proceed with ablation of the ...

Background
The most common complication of alcohol septal ablation (ASA) is transient periprocedural high-grade AV block (HGAVB). To date, no long-term follow-up of cardiovascular implantable electronic device (CIED) utilization after ASA has been reported. We hypothesized that CIED dependence on long-term follow-up can be predicted by ECG or proce...
